Let's pretend we are deeper here. Do we take a cheap one off and push any non straight card? Such a strange amount to raise a check raiser.

Nope, get as much money in this pot as is allowed, as fast as they allow you to do it. If he happens to have the case Jacks, (which since it has happened to me fifty times, I'm sure he does) that's the way the cookie crumbles.

Yeah just get it in.
